COMBINED HINGE, FASTENEI, .AND SHUTTER-OPENER.

Specicaton of Letters Patent No. 6,059, 'dated January .23, 1849.

To all whom, t may concern: t

Be it known that I, A. S. PELTON, of Clinton, in the county of Middlesex and State of Connecticut, have invented a new and useful apparatus for opening, closing,

. and fastening window-blinds from the inside of buildings without opening the sash,

called Peltons improved window-blind hinge, which is described as follows, reference being had to the annexed drawings of the same, making part of this specification.

Figure 1, is a perspective view of the shutter opened back against the wall. Fig. 2, is a perspective view of theV lower half of the hingethe upper half being detached from it. Fig. 3, is a plan of the upper half of the hinge inverted. Fig. 4:, is an edge view of the upper half of the hinge. Fig. 5, is a plan of the jointed and cogged propelling rod. Fig. 6, is an edge view of said rod--the handle being turned down. Fig. 7 ditto showing the plain side of the rod. Fig. 8 an edge view of the upper half of the hinge showing the cogs and inclined planes.

Similar letters in the several figures refer to corresponding parts.

I am aware that hinges Vhave been cast with cogged segments with which a cogged bar or screw rod have been geared `said cogged bar extending from l the hinge through the Window frame into the interior of the apartment where it has been fitted with a handle, by which it is moved back and forth or turned on its axis when formed with a spiral thread as in the case of Vardins hinge. I am also aware` that hinges have been cast with an upper and a lower circular flange on the knuckle notchedv and cogged on the faces that come together for holding the blind securely in any required position. But I am not aware that'hinges for opening, closing and fastening window blinds from the inside of buildings, while the sash is down, have been cast with a cogged segment of a circle and inclined planes combined with a circular notched plate forming the upper half of the hinge said inclined planes being made to corre-l spond with inclined planes formed onthe cogged propelling bar for lifting the upper part of the hinge so as to disengage the tooth of the lower part from the notches of the upper half of the hinge/ simultaneously with turning the said upper half by the same cogged bar. Y l

Heretofore the parts of the hinge Vhave. i

been disengaged by the use ofa lever fixed to the outside of the frame and had `no agency 1n turning the blind-the window sash having to be opened in order to move the blind. `Nor am .I aware that anypropelling rod has ever been constructed with a hook at its outer extremity to pass into a notch formed on the underside of the plate when the shuttle is closed and the rod drawn in to prevent the upper half of the hinge be# L cast'in the form of a circular box A, with 'f f a lperforated flange B, by which 'itrisvfastened'to the outside ofthe window frame,l by screws, `and, a'v studC in its center (over which is slipped the upper half of the hinge and rupon which thesaid upper half {mms}4 c,

which the propelling rod is to be passed and a vertical tangential ystraight plate VA3 touching the periphery of the box between said openingsand joined to the bottom plate A-by anV extension of the latter' until it meets the saidf vertical tangential plate thus formingva straight tube in which the propelling rod plays back and forth in opening and closing the blind.` The Adrawing'rep'- resents this tube, Aor way for the propelling rod to move in', as extending through the.

window frame and circularlboxhorizontally "and at fight angles t0 the side` or front of the building. w

joined-"to the upperfedge ofthe box by triangular segments cast with: the box. On .v i

one of them is cast a tooth D to fit into notches inthe periphery ofthe circular plate the saidupper half is prevented yfrom turning on its ax1s. IA'fprojection E is Vcast onthe flange to strike against thetop of the circular plate of the upper half of the hinge when `attempting to separate it from the lower half. Y

The circular plateF of the upper half of Y l the hinge is cast of greater diameter than the circular box and turns upon vthe edge of the latter, having 'a flange Gr by Vwhich it is screwed tov the'shutter or blindl Y f l l 91sl 1 The"upperedge of the tangential platel is 4 yloo y of the upper half -of the hinges by which i inclined planes I, J, commencing on the j line of its diameter and extending around on a circle concentric `with the circle of the plate and the circle of the cogs and bef-VV tween the same and the deepest ends of said inclined planes extending 'down from the" under side of the circular plate (with which they are cast) about half the depths of the cogs for the purpose of being acted on by the inclined planes formed on the propelling rod hereafter described in lifting the upper half of the hinge. A- projection K is cast on the same circle with the inclined planes and of the same depth and midway between them for the purpose of bearing on the upper surface of the propelling rod while opening or closing the shutter.` The periphery `of the circular plate con7 tains two notches L, L', that are toadmit the projections on the lower half of the hinge when the shutter is opened or closed. A guard plate M is cast on the periphery of the aforesaid plateV extending downward vertically in a position to come directly over the outlet of the tube in which the propel# ling rodmoves when the window blind is closed to prevent access to the rod from .the outside. In the thick end of Vone of the inclinedplanes is made a notch N Ato yadmit a hook formed on the end of the propelling rod to prevent the parts of the hinge from being separated when the blind is closed and the, propelling rod is drawn in and folded on the inside.

The propelling rod VP for opening and closing the blind is a metallic bar hinged near the middle of itsv length at P and cogged on the side next the cogged segment and between' two Vinclined planesPs, P4, formed in the upper side of 'saidxr bar and having a hook P2'onfits outer extremity for hooking intothe notch N laforesaid in the inclinedplane ofthe cogged segment, when the blind is closed for holding the parts se-y curely together. a f

There should be one'cog lessi in :the rack than the segment and these cogs should extend from one inclined plane tothe other. The slope of the'inclined planes :P3 P4 (which are formed on the upper side ofthe bar) extends in contrary ldirections from the ends of the rack. The side Vof the bar opposite the inclined planes should be hol# lowV as at P5 P6 to allowlthe bar to'move longitudinally the distancerof the inclined planes without coming in rcontaotwith'the cogs of the segment in lifting the upper half of the hinge. The .inclined planes "are formed by notching thefupper side'of the propelling bar. z

A' hook R isMinserted -into theishutter which drops overf-a stop S inserted into the sill of the window frame when the shutter is closed and when the notch in the periphery of the circular plate comes perpendicularly-'above the. cog on the lower part of the hinge above described at the moment of ythe descent of the upper` half of the hinge.

'A lsimilar hook is inserted intothe opposite side of the shutter (not shown in the drawing) which drops over a hook fixed to the wall of the building when the shutter is opened back against the wall as represented in Fig. l, the descent of the hook taking place simultaneously with the descent 'of the shutter, upon the opposite notch in the circular plate coming directly j over the aforesaid cog when theshutter is turned a half revolution. The first named hook prevents the shutter beingopened until it be lifted by the propelling rod and the last named hook holds the yshutter securely against the wall until raised by said rod in closing it. The upper hinges of the shutters are made similar to the common slip hinges, or otherwise. i

Operation: The window vblind 'being closed-straighten the propelling rod P and move it outward: this movement will cause the inclined plane P3 next the hook P2 to press against the inclined plane J of ithe upper half of the hinge nearest the flange, causing it to rise with the blind, at the same time disengaging the hook Plon the end of the rodfrom the mortise in the segment and the hook R in the blind from the stop Sin the sill and the circular plate F from the cog D on the edge of the box and bringing the cogs of the rod into gear with theicogs of thefsegment by which the upper half ofi` the hinge will be madeV to turn onthe center pin 4C while the inclined planes I and J `and projection K between them will slide.. upon f the vtopwof` the rod until the blind has been l turned half a vrevolution when the opposite inclined plane I will descend into the notch i ofthe rod, causing the blind torise and move p around toits'fo'rmer position and to descend bringing the" plate F into lock withthe cog D and the hook R over the stop Sand to lock the upper and lower parts of the hinge together by the hoolrPgron, the end of the rod P entering the mortise in the end of the *inclined plane. The inner half of the rod is then turned downto a position parallel with the window casing and out of the way. This also prevents the rod from being moved from theoutside, even werethere no guard plate; but when the rod is drawn in, the

guard;M is moved aroundfby `the circular l plate and brought over the outer end `ofthe mortise in which the rod moves which also without raising the sash, I will here y state that I do not pretend to be the rst inventor of a hinge to accomplish the abovenamed objects by rack and pinion or by screw, but

What I do claim as my invention and desire to secure by Letters Patent, is-

The peculiar manner in which I construct the hinge and propelling rod combined therewith, by which I unfasten, turn back, and secure window blinds, by simply mov-y ing the rod outward; and again unhook, turn, and refasten the said window blinds by reversing the movement of the rod without raising the sash in either operationthat is to say I claim constructing the rod P with spaces P5 P6 in the side and inclined planes P3l P4 in the top thereof at ythe endA of the rack in combinationwith the inclined planes I, J, on the upper halfof the hinge-arranged and operating in the manner and for Y the purpose above described.

2. I also claim the before described mode of locking the upper and lower parts of the hinge by means of the hoop P2 on ythe end of the rod P entering a corresponding groove in the upper part of the hingethe rod bethrough the mortise inthe box A of the lower half of the hinge, by which mode of fastening, the blind is elfectually -secured against being raised or opened from outside the building as described.

.In testimony' whereof AI have hereunto signed my name before two subscribi-ng witnesses.
